The three isotopes of hydrogen are commonly called hydrogen ('H), deuterium (*H), and tritium ('H). Hydrogen and deuterium are stable while tritium decays via B emission with a half-life of 12.33 years. (a) Find the binding energies for the 3 isotopes. (b) Find the binding energies per nucleon for the 3 isotopes. (c) What does tritium become when it decays? Write down the decay equation. (d) Is the tritium daughter nucleus stable or unstable? (e) What is the maximum kinetic energy (in eV and Joules) that the emitted electron could have from the radioactive decay of tritium? (1) Suppose a sample initially has 10% tritium atoms. What is the initial activity of the sample (in dec/sec and in Curie)? (g) How long would it take for the activity to reduce to one tenth of its initial level?
